The young news reporter Goldilocks is at is again she is trying to find out how bears live life this time she is finding out witch chair bears sit in the most.her purpose (reason)the purpus of this experiment is to find witch chiar the bears sit in the most. So one day she was going to the lad when she found the perfect bear house.she knocked on the door but no one answered. So she invited herself in.She observed (what she found out) three chairs so her levels of IV (the things that change) were wood mettle and cushioned. she inferred ( things that may happen) that the one the bears sat it the most was the cushioned one was a wood chair witch looked like none had sat in it for a long time. The next thing she saw was a mettle chair she decided to use her senses. It looked fine, it smelled normal, she decided not to test it ,but it felt like a freezer . So then she looked at the next one it was cushioned (things that stay the same) were sit in it for only 5 min, and to make sure there was no distractions.after she finished she found out the bears like cushioned chairs more than wood chairs.
